Although she hasn't been on the show in a long time, I used to love Teresa Blake's (Gloria) hair on AMC - sorry the only picture I found:Shannon Kane (Natalia) on AMC:

Her stepmom, Angie (Debbi Morgan), although she changes it constantly, including a lot of straight styles:

Can't find a photo where it looks like what I'm talking about, but on the rare occasions where Susan Lucci (Erica) wears her hair naturally curly on AMC, I think she looks much better, mainly because it makes her look fresher and younger. This was the closest I could find, though it looks more styled than when I mean - as if they've used Benders or something:

Thorsten Kaye (Zack), also from AMC, although he usually looks more like the second pic in recent years:

Like everyone else I like his soap wife, Alicia Minshew's (Kendall) curls. His first pic above is from back in the day when he was playing Patrick on OLTL opposite his now real life SO, Susan Haskell (Marty) - as good a picture as I could find:

Kamar de los Reyes (Antonio), though he's gone from the show now - not the best pic to see his curls

Sonya Eddy (Epiphany) on GH!

Like everyone else, I love Laura Wright's curls on GH - have ever since she debuted on Loving almost 20 years ago. Our hair was almost exactly alike back then except for the color.

New character Maya Ward (Annie Ilonzeh) has gorgeous curls

as did Marisa Ramirez who played Gia Campbell, though hers was usually in braids as here; now she wears it straighter

Though she looks scary now, as in this picture, Jaclyn Zeman (Bobbie) used to have lovely thick, bouncy curls
